Wow. Welcome to vector. I'm not too good at troubleshooting and don't really know where to start. What version did you install and how did you install it? What does "looks like dos" mean? Assuming it means that you are not getting through to the gui, then you might try running vasm at the prompt (after going to root) and run the xconf program.

Was about to post the same. computer spec would help and as mentioned version you installedIf you booted and reached multiuser then got an xorg error try pressing ctrl plus alt plus del and rebootat the boot you will have option for linux tui and gui choose tui ( text user interface)when you reach the prompt as mentioned type rootroot passwordvasmselect xwindows(ok)xconf (ok) and try the first one autothen exit correctly using the last options in the list and reboot
